Welcome to Health after Oil (HAO), a place for news, opinion, research, discussion, networking, planning and action in response to the unprecedented and sweeping challenges peak oil, energy decline, and population pressures poses to human health and the institutions whose purpose it is to protect and promote human health. We invite submissions -original content and links- about energy and health and related fiscal/economic and environmental and ecological issues. We note in particular that: 1) Climate change and peak oil are indivisible threats, both stemming from reliance on fossil fuels; and 2) The fiscal and economic crisis now enveloping world economies are intertwined with population growth, energy decline and resource depletion. Infinite growth cannot continue on a finite planet.
